Investigators Believe Andover Doctor Filmed Child Porn Overseas

ANDOVER (CBS) – Every light was on in the Andover house of Doctor Richard Keller Thursday night, hours after federal investigators left the scene.

They were back because of what they found the last time they searched here.

Back in September, the 56-year-old Children’s Hospital pediatric endocrinologist was arrested at his home, and charged with owning hundreds of photos and DVDs of child pornography.

But as investigators have studied what they found in his home, they’ve become worried that Dr. Keller didn’t just collect child porn; he may have been making it.

Keller’s across-the-street neighbors are dumbfounded. Said one of them: “Unbelievable! what kind of craziness is going on?”

Based on videotapes the investigators say they found in the home, it looks like Keller traveled to a nudist resort in France in the late 1990s. That’s where investigators think he secretly videotaped several hours worth of young boys playing naked on the beach and in the pool.

Thursday, detectives were back at the Keller home to look for evidence of those recordings.

In addition to the physical recording equipment, detectives are also looking for a silver watch. In the French videotapes, all that can be seen of the man who made the recordings is part of an arm, and a silver wristwatch. The warrant that allowed agents to collect evidence today specifically authorized the collection of every men’s watch inside.

Keller, who previously spent nearly two decades as medical director of student health services at Phillips Academy in Andover before quitting in 2011, now sits in federal jail, as prosecutors appear to continue to build their case against him.
